[10] Nor does the letter of 10 May address many issues that the respondent contends needed to be addressed such as, the date of the stocktake, the name of the stocktaker, what happens to the stock until the stocktake was completed, who was to pay for the stocktake, what arrangements should be made for assignment of the premises leased including the releases of guarantees and the provision of new guarantees and covenants to comply with the lessor's requirements, the settlement date relative to such releases, control of the business in the interim, the return of keys, liability for tax and wages and a significant number of other matters detailed in paragraph 5(b) of Ms Somerton's affidavit. It may well be that many of those are clauses that might be described as non-contentious, the absence of which may not necessarily lead to a conclusion that agreement has not been reached where the substantial terms have otherwise been agreed; see e.g. South Coast Oils (Qld and NSW) Pty Ltd v Look Enterprises Pty Ltd [1988] 1 Qd R 680, 698-699.
